using threads with for-loops

[Klaus Neuner]

Hello,

I wrote a program that does essentially the following:

for rule in rules:
	for line in line_list:
		line = my_apply(rule, line)

line_list contains the lines of some input text.

To "apply a rule" always means to

  1. do some regex matches on line
  2. substitute something in line


My question is: Given this "architecture", does it make sense
to use threads? And if so, how?
